is quite thin saidscrew v Application filed Augustl provemen't' inCircuit-Wire Terminals, of

which the following is a specification.

Certain for s of circuit-wire terminals heretofore ma d e consists ofplates having means at one or both ends for connection therewith of oneor more circuit-wires, and

having minal for connection therewith of a circuitwire' consists of a binding-screw. which extendsthrough a screw-threadedhole in theend-portion of the plate, and as the plate has but a short bearing andeasily becomes loosened. Furthermore, such a; terminal is liable to turnon its attaching-screw and thereby engage adjacent terminals or objects,causing electrical troubles, also produces a strain on the circuit-wiresand their connections .with the terminal.

-This invention relates to improvements in circuit-wire terminals ofthis type,-and conthreaded walls thereof;

sists in providing one end-portion ofthe attacbirig-pr-rtion of theplate-with an overturned portion, and forming screw-threaded holesrespectively in said overturned portion and the attaching-portion, whichare ar ranged in alinement', and employing a binding-screw, 'inade; longenough to extend through. both holes and jto engage the and preferablylong enough to 'projecta short distance be. low thejbottom of theattaching-portion of the plate to enter a hole in the support to whichthe'terminal is attached, thereby insuring a long'bearing for thebinding-screw to prevent it from becoming easily loosened,

and also to preventthe. terminal from turning on the attaching-screw. Asthe inven tion involves essentiall one end of the plate only the otherend thereof may be fprovided with any form ofcircuit-wire connection ormay be devoid of a circuitwire connection.

The terminal consists of an elongated plate of any suitable length andwidth, but

usually made of sheet metal. It has a sub- ZrEeLnn, 5
